Novel process for the preparation of spiroheterocyclic pyrrolidine diones

ABSTRACT

A process for making certain spiroheterocyclic pyrrolidine dione derivatives.

The present invention relates to methods to prepare spiroheterocyclic pyrrolidine diones, which are useful for combating and controlling pests such as insect, acarine, mollusc and nematode pests, to new phenylacetylamino-carboxamide intermediates useful in such methods and to processes for preparing such intermediates.

Spiroheterocyclic pyrrolidine dione derivatives for combating and controlling pests such as insect, acarine, mollusc and nematode pests are disclosed, for example in WO 2009/049851 and WO 2010/066780.

A new method for preparing these compounds has now been found, which uses a novel intermediate. Methods of preparing spiroheterocyclic pyrrolidine dione derivatives are described in WO 1998/005638, WO 2004/007448, WO 2009/049851 and WO 2010/066780, with the present invention offering unique methods to prepare such compounds using less process steps (presenting therefore advantages such as higher thoughput capacity and lower amount of waste) as well as more attractive conditions (for example, avoiding the use of very toxic HCN or equivalents). It has been found that the novel intermediate can be converted into spiroheterocyclic pyrrolidine dione derivatives via inter-molecular activation. This new process is particularly beneficial as it uses less-expensive reactants. Further, the present invention is suitable for commercial-scale production.

Accordingly, in a first aspect, the present invention provides a process for the preparation of a spiroheterocyclic pyrrolidine dione compound of formula (II)

When A is hydrogen, the source for the reagent (V) may be ammonia (NH₃) or an ammonia equivalent such as for example ammonium hydroxide NH₄OH, ammonium chloride NH₄Cl, ammonium acetate NH₄OAc, ammonium carbonate (NH₄)₂CO₃, ammonium formate HCONH₂, and other NH₃ surrogates.

In most cases, it is advantageous to conduct the reaction in a suitable solvent (or diluent). It is preferred that the molar concentration of the each of the reactants in the reaction mixture is higher than 0.1M, particularly preferred are concentrations higher than 0.5M. Suitable solvents (or diluents) include polar solvents (or diluents) such as alcohols, amides, esters, ethers, nitriles and water, particularly preferred are methanol, ethanol, 2,2,2-trifluoroethanol, propanol, iso-propanol, N,N-dimethylformamide, N,N-dimethylacetamide, dioxane, tetrahydrofuran, dimethoxyethane, acetonitrile, ethyl acetate, water or mixtures thereof. The reaction temperature could be from −50° C. to 150° C., preferably between −20° C. and 100° C., most preferably between 0° C. and 60° C. The reaction time is usually between 0.1 hour and 96 hours, preferably between 1 hour and 24 hours. Various catalysts and additives may be used such as dehydrating agents (Na₂SO₄, MgSO₄, molecular sieves), water, Lewis acids (Ti(O-i-Pr)₄, Sm(Otf)₃, Yb(Otf)₃, ZnCl₂, ZnBr₂). The amount of a catalyst or an additive is usually between 0.01 and 1 molar equivalents.

In an alternative embodiment, a compound of formula (I) is treated, in the absence of a compound of formula (III), with a suitable base, in an appropriate solvent (or diluent) or solvent (or diluent) combination to produce the compound of the formula (II).
